Satellite remote sensing of Arctic surfaces
Lead: Angelika Humbert, AWI

The objectives of this WP are:

  • to quantify the presence, and present day lifecycle of anthropogenic contaminants ((PBDE, PAH, PCB
    and Persistent Chemicals of Emerging Global Concern), mercury and heavy metals (Cr, Pb, Cd), along
    with black carbon (BC)), through annual snow and aerosol sampling. This will be obtained from
    dedicated ice core samples for comparison.
  • to continue atmospheric Hg monitoring in polar regions and perform an in-depth evaluation of the
    mercury cycle,
  • to perform modelling of halogens/ozone and analyze their influence on arctic chemistry and contaminant
    cycles, including Hg.
  • to study the exchanges and interactions of persistent contaminants between different polar
    environmental compartments

The current and upcoming satellite missions will greatly enhance our capability of Earth observation, which in polar areas with a very sparse in-situ station network will give us spatial coverage to monitor the large area.
